Hello gophers,

We have just released Go versions 1.19.3 and 1.18.8, minor point releases.

These minor releases include 1 security fixes following the security policy:

  • syscall, os/exec: unsanitized NUL in environment variables

    On Windows, syscall.StartProcess and os/exec.Cmd did not properly check for invalid environment variable values. A malicious environment variable value could exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" set the variables "A=B" and "C=D".

    Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue.

    This is CVE-2022-41716 and Go issue https://go.dev/issue/56284.

You can download binary and source distributions from the Go website:
https://go.dev/dl/

To compile from source using a Git clone, update to the release with
git checkout go1.19.3 and build as usual.

Thanks to everyone who contributed to the releases.

Cheers,
Matthew and Heschi for the Go team

I think it's important to report that  go1.18.8.windows-amd64.msi doesn't match the published sha256 checksum.

Thanks, good catch. We accidentally signed the installer twice, uploaded the first one, and posted the checksum for the second one. We'll correct the checksum.

Hmm, I do see a matching checksum
(6d38668862bf9772c0c1c1e0f26aa5dedea9825b33f763b81ccc4aa63df2cef9) for
go1.18.8.windows-amd64.msi.

Yep, we fixed the checksums yesterday for all the Windows installers.
